The answer is x=3 I am pretty sure
Answer:
3(x-1)
Step-by-step explanation:
you need to out the x minus 1 in brackets as you multiply the whole thing by 3
The average number of miles she would have to meet her goal will be 2.62 miles each day.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Keilantra plans to pedal her bike 28.8 kilometers each week. She has already written a great deal. assuming she rides for another four days.
Let n be the number of days required more. Then the equation is given as,
⇒ 28.8 / (7 + n)
⇒ 28.8 / 11
⇒ 2.62 km each day
The average number of miles she would have to meet her goal will be 2.62 km each day.

Using proportions, we have that:
- 125% of last year's attendance is of 270.
- 25% of last year's attendance is of 54.
- 100% of last year's attendance is of 216.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
We have that last year's amount is of x, and 125% of that is 270, hence:
1.25x = 270
x = 270/1.25
x = 216.
100% of last year's attendance is of 216.
25% of last year's attendance is given by:
0.25 x 216 = 54.
